Copper and zinc extraction by ammoniacal leaching from microwave-roasted Cu-Zn-Pb sulfidic tailings followed by recovery of copper and zinc by ion flotation and precipitation. Introduction Tailings are mixtures of fine-grained unwanted fractions after mineral beneficiation of ores at a mining site that are considered as a waste [ 1, 2 ].
A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a copper-nickel concentrate comprises pulping the ore with water to form a slurry, conditioning the slurry with an aqueous solution of SO 2 (H 2 SO 3 ) equivalent to from about 2 to about 4.5 pounds of SO 2 per ton of dry ore for a time ...
The recoverable copper in the ore is mainly stored in chalcopyrite, chalcocite and a small amount of copper-bearing sulfide minerals such as copper blue and azurite, with a copper content of about 1.72%. copper ore dressing plant Generally speaking, modern copper ore beneficiation technology includes flotation, microbial leaching, segregation ...
Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The experiment was conducted by means of a Jameson cell. The

A froth flotation method for the recovery of copper, nickel, cobalt, oxide, silicate, sulfide, arsenide, and antimonide minerals from their ores over iron sulfides, silica and silicates, as well as for the recovery of silicate minerals of lithium, sodium, potassium, and caesium over silica and feromagnesian silicates, and for the recovery of potassium halides and sulfates, strontium, and ...
Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size (d), the flotation time (t), the type of collector (k), and the dosage ...
The most common ore used in the copper extraction is Chalcopyrite (CuFeS 2), also recognized as Copper Pyrites and other such sulfides. The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible. The concentration of ore is required, and the Froth Flotation method is used for this process.
In a plant where the flotation capacity is fixed, this means lower copper recoveries. Dispersants such as sodium silicate, polyacrylates, and sodium hexametaphosphate are often used to minimize fine gangue slimes bubble adhesion and minimize impact on copper recovery.
Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semi-quantitative mineralogical analysis of the flotation tailings revealed significant content of carbonate minerals (approximately 20-25 %), indicating high acid neutralization capacity.

The ore grade refers to the fraction of a useful element within the ore. It can also be used for gangue as the proportion of a non-valuable substance, but generally, when we use the term grade, we mean the grade of a valuable element. For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper.
